Product structure and performance synopsis
Three-dimensional eccentric hard sealing butterfly valve is new product, which product by this company with log service life and energy saving. The product measures up national standard of JB/T8527-1997(metallic sealed butterfly valve) or API609-2004 Butterfly valves, double flange, lug-and water-type, GB/T 13927-1992(general valve pressure test) and regulations about other relative standard of valve.
This product is composed of body, disc, gasket, operating device etc. The structure design according to principle of three dimensional eccentricity, new processing technology of flexible seal and hard & soft multiple layers seal, when the butterfly valve operation, it can reduce the twisting force, reach to the function of saving labor and energy. Thereby ensure holistically antisepsis, high temperature-resistant, wearable reliability of valve. The main characteristic such as:
1 Particular structure, small bulk, operation skillfully, laborsaving, conveniently;
2 Seal reliably, it can reach to gas seal with no leakage;
3 Flux capability to direct line and best adjusting capability;
4 It adopts the principle of three-dimensional eccentricity, and facing near zero wearing, prolong service life of valve;
5 Appropriate differ temperature and thereinafter of 6.4Mpa pressure class, resistant wearable medium tube and so on;
6 Wide applied range, it can use medium such as: Water steam oil air gas etc.
